Detailed specifications

General performance parameters such as number of shaders, GPU core base clock and boost clock speeds, manufacturing process, texturing and calculation speed. These parameters indirectly speak of performance, but for precise assessment you have to consider their benchmark and gaming test results. Note that power consumption of some graphics cards can well exceed their nominal TDP, especially when overclocked.

Pipelines / CUDA cores	96	384
Boost clock speed	1650 MHz	1425 MHz
Number of transistors	no data	4,700 million
Manufacturing process technology	10 nm	12 nm
Power consumption (TDP)	25 Watt	30 Watt

Form factor & compatibility

Information on Iris Xe MAX Graphics and T400 4 GB compatibility with other computer components. Useful when choosing a future computer configuration or upgrading an existing one. For desktop video cards it's interface and bus (motherboard compatibility), additional power connectors (power supply compatibility). For notebook video cards it's notebook size, connection slot and bus, if the video card is inserted into a slot instead of being soldered to the notebook motherboard.
